Version A. A freeway section has 4 lanes on each direction. Lane width = 11 ft. Right-side shoulder width = 4 ft. A total of 5 ramp exits/entrances are found over the 3-mile section. Annual average daily traffic (AADT) is estimated at 60,000 veh/day. Evaluate the LOS using the 30th largest design hour volume. Other parameters are listed below: This freeway serves primarily commuter traffic. Trucks & buses account for 10% of total traffic; RVs account for 0% of total traffic. PHF = 0.85 Directional factor = 0.65 Rolling terrain
